Not that it maters but another ham and myself have been licensed for 40
years.

We ran across somethng the other day that we had not seen before. We live
about 10 to 15 air miles apart. I have a vertical dipole at 35 feet on a
tower. He has 2 differant FM rigs and vertical dipole wire antenas in his
attic about 50 feet apart. I can work him direct on 6 meters with him
mobile in his drive way. A couple of days ago we could work with his attic
antenna.
He built another antenna , so he has two antennas and rigs. A Midland and
GE comercial unit that puts out 40 watts each. I check the sensitivity on a
HP 8924C and they both seemed to be as good as a Midland I was using.

It rained and now he can not hear me, but I can hear him fine on either rig
and antenna of his. I switched to an Icom 706 at 100 watts out and and
checked the reflected power is about 2 watts. At this time, he could tell
when I was transmitting ,but not understand me. We were co-ordinating over
2 meters.

I also switched to an OCD antenna at 50 feet and could hear him. The
internal tuner on a 746 pro tuned it,but he could not hear me on that either
and he was about S-5 on the meter.

Do you think we have discovered one way shingles ???

Anyone else seen anything like this ?

His antenna pre-amplifier has died.

There are no antenna preamps. All our rigs just go from the output up some
coax and to the antennas.
The rigs are just older comercial Midland XTR and GE MLS. They have been
reprogrammed to 6 meters.

He has two seperate antennas and rigs. I had just checked all rigs involved
in the last two weeks with an HP 8924c test set and all were putting out 30
to 40 watts and the receivers would open the squelch at under .3 uV. I don't
recall the exect valuse, but they met the origional specs.
I know the rigs are on frequency to less than 100 hz. Also all were verified
that the receive and tramsmitt matched what we have the chanels set for.
The midlands were all programmed off the same programming file and computer.

More likely you've discovered a nearby lightning strike
and now his RCVR front end is blown.

I do not recall any thunder storms in the area. If it blew the front end,
it would have had to do it to two rigs and the antennas are in the attic.

We will check out the sensitivity again at the first chance.

My doctor gave me Acyclovir for shingles.

Then you must be omnidirectional again. Good for you.

Either his receiver is dead or it is suffering interference.

Now that is an idea I have not explored.

A six meter repeater was just put on the air about 5 miles from him and
sometimes there is a power pole that generates enough noise at the repeater
site it desenses the repeater receiver. We are working with the power
people now.
We do not hear it on the repeater, but an AM receiver pickes it up very
well.

I am sure it is not this noise as it is too far away, but he may have a
local source that is causing a problem.

If the 6 meter receiver has a noise blanker, he could be hearing so
much noise that the receiver acts like there's nothing to hear.
